Gas Monitoring Badges are lightweight colorimetric — ideal for both personal and area monitoring. Designed to accurately provide immediate results while minimizing the effects of humidity and air velocity. Each ChromAir badge shows exposure levels. The scale printed on the badges is based on exposure dose. Badges attach easily to shirt or lab coat collars — order badge clips separately
